The TUALAJ 8300 CRPA GNSS anti-jamming system from TUALCOM provides jam-free GNSS performance and resilient PNT for mission-critical operations. Using an 8-element CRPA, an advanced digital controller, and proprietary beamforming algorithms, it suppresses interference from up to seven directions across three frequency bands. The protected frequency set is selectable from available options, ensuring optimal system adaptability for diverse operational requirements.
Supporting both civil and military GNSS receivers, the TUALAJ 8300 integrates easily across land, sea, and air platforms, including unmanned and fixed installations. Optional embedded GNSS receiver capability allows SBAS utilization for enhanced precision and reliability. Two CRPA antenna configurations are available to meet specific size and weight requirements, and the system further improves protection through adaptive notch filtering and pulse blanking. Built to MIL-STD-810G and MIL-STD-461F standards, it provides assured navigation for defense and critical infrastructure platforms.
